4FIZJO Slam Ball 15 kg medicine ball
The 4FIZJO Slam Ball is a 15 kg medicine ball for strength training, circuit workouts and CrossFit. This version measures 27.5 cm in diameter and features an Anti-Bounce system to prevent rebound after impact with the ground.
Grip and impact absorption
The reinforced PVC shell resists abrasion, while the non-slip surface and raised rings help maintain grip with wet hands. The sand and iron-filings filling does not occupy the entire interior, allowing the ball to flatten on landing and absorb impact. A safety valve helps protect the shell from bursting when impacts increase internal pressure. The valve also allows the internal pressure to be adjusted.
Added weight for varied exercises
Use the ball for warm-ups, strength work, isometric exercises and balance exercises. It can also serve as an added weight for squats, forward and reverse lunges, abdominal crunches, torso twists and ball raises performed standing or lying down.
